Inventor: NEHL WOLFGANG
IPC: G11B33/04
Filed: 1991-10-25
Abstract: 2.1 In the case of known storage devices, the recording medium is transported by a slide, which can be displaced by means of spring force, into a removal position on the front side of the storage device, the slide being extended with the recording medium placed on it out of the housing to such an extent that the recording medium can be grasped. After removal of the recording medium, the slide is pushed back again to avoid projecting parts. 2.2 In order to be able to dispense with pushing back the slide after removal of the recording carrier, the storage device is equipped with a locking mechanism which, in the storage position, engages in the housing of the recording medium. Furthermore, even in the removal position, the entire slide is in a withdrawn location in the storage device. <IMAGE>
